I don’t buy milk, so I have no idea what is costs, but I do buy bread...and guess what. I have NO IDEA what it costs!! I just pick out the lite wheat any brand and I never check the price. I couldn’t tell you if it is 1.50 or 2.50.
I buy the kinds of bread that members of my family like. Sometimes they're on sale. Sometimes they aren't. So the price can vary quite a bit...by as much as a dollar or more.
